[labnetwork] [EXTERNAL] Re: Automatic gas shutoff at the source

[Ahad Syed]

Hi Kostis,

The response is same for KAUST-NCL. The fire alarm will trigger the TGM and that will turn off the valves, gas cabinets and VMBs. And vice-versa as well. Any TGM alarm from the NCL will trigger Building evacuation through the Fire System.

All the best,
Ahad

Hi Kostis,

Here at UDel it has been mandated that a fire alarm input to the TGMS closes all gas valves.

Dear Labnetwork colleagues,

We are reviewing our emergency procedures and I would like to ask, specifically for your hazardous and toxic gases, in the case of a fire alarm being triggered, if you make use of the building's Fire Alarm Control Panel (FACP) respective signal to automatically shutoff gases at the source.

We have at our disposal a range of engineering controls to shutoff gases at the source, but I am specifically interested to learn if the method of using directly the fire alarm signal has been mandated or otherwise chosen in your setting.

Thank you in advance for your consideration,
Kostis
